Today Corbett talks with Chris Dorsi, founder of the Habitat X Thinktank, about the state of performance-based building in Europe and what the construction industry needs next. *Listeners get a whopping $675 discount off Habitat X registration until June 15 by using code Corbett375.

Today Corbett takes you on a tour of performance based building from a sampling of builders around the world, and realizes that the millionaires are going to be very angry when they realize what they're paying for isn't nearly as good as the affordable housing to be had on the other side of the tracks. Hosted by Corbett Lunsford at the International Builders Show (IBS) in Las Vegas and the Michigan Habitat for Humanity HOMES Summit, January 2015.

Today Corbett talks with Russell King of Sierra Building Science about the labratory of California, where they've been trying to whip and incentivize efficiency like nobody's business. Are Manual J, Manual D, Manual S, window placements and sizes, and a menu of prescriptive energy code requirements actually leading us toward perfection?

Today we talk with Colin Genge, founder and CEO of Retrotec, about the history of air leakage testing, how the tests really work (and what they doesn't actually test), and using home performance diagnostics for playing competitive poker. Hosted by Corbett Lunsford of Green Dream Group in Chicago.

Today we talk with Chase Ming of All Development in Alabama about how to use overcommunication to make more money doing better work for happier clients. A real builder doing real business with real clients, in a state that's just starting the journey into performance codes.

Today we talk with Kerry Langley of Synovus Mortgage about how his company collaborated with Southeastern builders, HERS raters, and homebuyers to make an absolute killing for everyone involved. Corbett: "Why hassn't everyone been lending money this way?" Kerry: "I have absolutely no idea." YOU NEED TO HEAR THIS.
